PPP takes the system over :(

[-=Nihr0M=-]

Hello, I have a 5.2.1-Release.

The problem is, when I start PPP -auto <my_script> and my modem 
connects, 
when tcp transaction is going (e.g I download a file or open a web 
page...) I'm not able to run any other
program (it seems like comp 'freezes'). That just sux... but when the 
action completes, all htese progs start ...
duh...

BTW, my system is Athlon 1200Mhz, 256Megs of RAM, 200 of 2500 mb free 
on HDD, external USR modem

Looking forward to hearing from you,

Slava
